Summary


Variables are very important in Integration Services. They are the way components communicate with each other. Variables provide a temporary location for storing data or objects. Variables also provide a way to preprocess settings before actually being used in the package. Variables are type safe but their value can be modified during execution if the new value is not of a different type than the current type of the variable. System variables are a special type of variable that exposes system settings and property values to components in the package and are usually read-only.
